I have spoken to Lady Thatcher’s Private Office regarding the story, and they confirm that the attack on Sarah Palin definitely did not come from her office, and in no way reflects her views. As a former aide to Margaret Thatcher myself, I can attest that this kind of thinking is entirely alien to her, and that such remarks would never be made by her office. She has always warmly welcomed like-minded figures in the United States, and has in the past met with numerous US presidential candidates and political dignitaries when they have visited London. But at the age of 85 she is now able to receive very few visitors at all.
There was never any snub of Sarah Palin by Lady Thatcher’s office. However, there has been a great deal of mischief-making and unpleasantness from sections of the liberal press in a vain and futile attempt to use Margaret Thatcher’s name to smear a major US politician.
